Objects of observation were 4-6 years old children of kindergarten having pertussis vaccination and exposed history. The children were at random divided into two groups: 76 children were vaccinated with DTP vaccine and 72 children were inoculated with placebo. The results of observation: there was no strong and abnormal reaction in the vaccinated children; two weeks and three months after emergent vaccination with DTP vaccine, GMT antibody of pertussis were increased 18.14 and 4.73 times more than before vaccination respectively. There were no differences of the attack rates average days from vaccination to onset, average days of cough (P greater than 0.2) within 21 days after vaccination between the two groups. The protection rate was 62.11% three months after vaccination. The results showed that the emergent vaccination with DTP to control the outbreak of pertussis was safe and effective.
